the human beings stop growing after some time but in case of plants it is not so they continue to grow.

takes too much food and energy to keep on growing after we hit maturity, so it isn't worth the biological tradeoff.
in the case of plants, they reach a certain height, and after that it's all the parts related to metabolism and reproduction that continue to develop.
genes just want to spread. they don't really care about the size of the organism per se. so reproductive capabilities are the top priority, not growth for the sake of growth.
so we aren't that different, actually. we share 70% of our DNA with a banana, FYI.

Plants also stop growing. They die just like people with semi-set life spans. We stop growing, mostly, after puberty.. which goes to say that biologically we're designed to procreate. Everything in the universe breaks down and decays. So you might say, once our bodies have reached their destination, the breakdown really begins because we're not replicating cells so fast anymore.

Even plants will stop growing after a certain No. of years, especially with hardwood. Otherwise it will reach up to the moon.

Because plants are different. They stop growing but it's not that obvious. When we reach a certain age, our growth hormones decrease or stop production. So..there you go.

Must be because our hormones and the other factors get diverted for other purposes like maintanence.... the skeletal growth stops after the fusion of epiphyseal end plates
